Improvement in picture-exhibitors



UNITED STATES SIMON GUERRIN, OF CONCORD, NEW HAMPSHIRE.

IMPROVEMENT IN PICTURE-EXHIBITORS.

Specification forming part of Letters Patent No. 158,065, dated December 22, 1874; application filed J nne 19, 1874.

To all whom it may concern:

Be it known that I, SIMON GUERRIN, of Concord, in the county of Merrimack and State of New Hampshire, have invented a new and useful Improvement in Panoramas; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings and to the letters of reference marked thereon.

This invention is a panorama adapted to be secured in the corner of the room, and to exhibit the picture or pictures upon the continuous sheet by the revolution of a roller in the usual well-known manner. Its novelty consists, mainly, in the employment of a spring of peculiar construction, in connection with the winding-rollers. It further consists, also, in certain details of construction, which, in connection with the foregoing, will be fully described hereinafter.

In the drawings, Figure 1 represents a front elevation; Fig.2, a transverse sectional elevation with a detached portion enlarged, and Fig. 3 an elevation of one of the windingrollers.

To enable other's skilled in the art to make and use my invention, I will now proceed to describe fully its construction and manner of operation.

A represents the case, made of any suitable material and proper size and form, and provided with the face-opening'a, suitably covered with glass for the display of the views upon the continuous sheet. B B represent the guiding-rollers, suitably journaled in the the top and bottom boards of the case, which are so arranged, relatively to the opening in the front of the case, as to guide the sheet in its movement in a plane parallel to the opening, as shown. C 0 represent the windingrollers, also suitably journaled in the boards of the case, and provided with projecting shafts c 0, adapted to receive the winding-key, and

also with roughened or toothed surfaces 0 c, as shown. D represents the spring of suitable material, consisting of the solid portion 01 and spring-arms d d, the latter of which are adapted, by their position and construction, to bear against the roughened portion 0 c of the rollers O G, as shown.

The operation is as follows: Movement being communicated to either winding-roller, according to the position of the sheet, the latter is drawn along, in rear of the face-opening, in such manner as to properly display the pictures upon its surfaces. By means of the spring it is delivered from one winding-roller only as it is taken up by the other, so that it is at all times kept tightly stretched and free from wrinkles.

The case is preferably made triangular in form, and is adapted, by means of proper holes in its back, to be readily secured in place.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination of the holding frictionspring D with the roughened rollers O 0, substantially as described.

2. The spring D, having the parts d d d, in combination with the rollers O 0, having the roughened surfaces 0 c, as described.

3. The picture-exhibitor described, consisting of the portable triangular case A, having the guidingrollers B B, winding-rollers O U, and spring D, constructed and arranged as and for the purpose described.

This specification signed and witnessed this 25th day of May, 1874.

SIMON Z GUEERIN.
